ALPHONSE A. SEBASTIAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO ANDREW HOFFMANMFG. 00., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CASEMENT-WINDOW.

Application filed June 25, 1919.

To all whom it may concern:

Be it known that I, ALrHoNsn A. Snsas- TIAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inCasement-VVindows, of which the following is a specification.

My invention has for its principal objects the provision of a sliding orcasement window embodying certain structural features which make forefficiency in weather exclusion, ease of operation, sightliness, economyof construction, and accessibility for adjustment and repair or renewalof parts, concealment of hardware fittings, proof against binding due tosettling of building, automatic adaptation of same to inequalities ofcasings, and capacity for installation in an ordinary boX window framewithout the remodeling or the substitution of a special frame as isordinarily required where a casement is substituted for double-hungwindowsu These objects are attained, in general, (1st} by providing anupper suspending or guiding channel having vertlcal dimensions over allnot exceeding the depth of the usual recess in the head between theparting strip and the stop, whereby 11o forming of a special groove inthe head is required for the housing of the channel; (2nd) by suspendingor grinding the hinged sash members from the channel by means of hangerbrackets which are attached to the edge of the sash instead of the sideface or the upper edge thereof, thus rendering the fastening screwsreadily accessible by partially opening the sash, as distinguished fromthe difficulty of access to such screws when the brackets are attachedto the upper edge and especially when the top of the sash is close tothe ceiling, and also entirely concealing the hardware fittings fromview when the window is in closed position as distinguished from theundesirably conspicuous fittings where attached to the side face of thesash; (3rd) by providing a guiding connection between the ends of thesash and the track or guide, which connecting medium has a verticallyadjustable and pivotal relation to the sash as well as provision forhorizontal play, whereby continuity of and free engagement with thetrack is in no wise jeopardized by irregularities of vertical orhorizontal dimensions of the opening, as when the upper Specification ofLetters Patent.

suspending track and the lower guiding track one or both sag, buckle orotherwise deviate from parallel right lines.

Other distinctive advantages of the new construction will be readilyapparent to persons acquainted with the practical require ments ofsliding window construction and the disadvantageous features of theprior art.

WVhile the present invention is illustrated and described as applied ina folding casement window composed of hinged units suspended from above,it will be obvious that it is also applicable to sliding windowscomposed of independent units, as also to folding and sliding doors;wherefore the accom panying drawing and the detailed descriptionpredicated thereon are to be taken in an illustrative and not in anunnecessarily limiting sense, reference being had to the claims as ameasure of the scope of the invention.

In the drawings, a preferred embodiment of the invention in a casementwindow is illustrated, wherein s Figure 1 is a horizontal sectionthrough a casement window;

Fig. 2 is a transverse vertical section on an enlarged scaleillustrating the invention as applied to a standard box window opening,such section being taken on the line of Fig. 3;

Flg. 8 is a front elevation of Fig. 2;

Fig. l is a fragmentary detail in perspective of the upper guiding trackor channel;

Fig. 5 is a similar view of the hanging bracket;

Fig. 6 is a similar view of the pivot plate;

Fig. 7 is a similarview of the lower guiding block;

Fig. 8 is a fragmentary detail in perspective of a portion of the lowerguiding track;

Fig. 9 is a fragmentary elevation of the window operating handle Fig. 10is a detail of said handle; and

Fig. 11 is a fragmentary detail showing a slight modification of thesill fitting.

Having reference to Fig. 1 of the drawings, the left hand end of saidfigure represents a substantially medial longitudinal section through acasement window of the present invention while the right hand side ofsaid figure representsa top plan view of a pair of the sash immediatelybelow the lintel, the observer being on the outside of the window. Atthe right hand of said'figure the dotted lines indicate the position ofthe two sash when partly open. In said figure the window j ambisrepresented at 11, the sill at 12, a window screen at 13, and thewindow frame generally at 14. The inner pulley stile is shown asreplaced by a filler strip 15 and the outer pulley stile as suppliedwith a filler strip 16. The parting strlp 17 forms the outer stopbetween which and the filler strip 15 seats the stile 18 of the easementwindow. The window in this figure is shown as composed of four slidingunits 19 hingedly connected 'together by hinges 2O at their adjacentedges in pairs, the adjacent stiles 21 of the two pairs arranged to abutwhen in the closed position of the window, the line of juncture beingcovered by the astragal 22 or, the adjacent stiles 21 may be hingedtogether in the same manner as are the units of the two pairs by hinges20.

In Figs.;2 and 3 the same construction is shown modified only to theextent necessary to show the adaptation of the invention to the mountingof the casement window in the standard box frame used in connection withdouble hung or doublesliding windows. Here the head of the window frameis repre sented at 23 and the sill at2t, the former provided on theinside with the stop 25 and the latter with the stop 26. Vhere it isdesired to equip such standard window frame with the sliding or casementwindow of the present invention, the guide channel 27 is placed withinthe recess in the lower face of the head originally provided for theaccommodation of the upper ends of the sliding sash. This guide channelbeing of limited vertical dimension is entirely received within said,recess without the necessity of forming a special groove or seattherefor. The guide channel held in position within the recess by'meansof the screws 28 has its lower face substantially flush with the lowerface ofthehead or slightly above the same. Th'efiller strip 29 is thenplaced in position between the said guide channel and the standard.parting strip 30 although this filler strip 29 may be omitted. A fillerstrip 31 is then preferably placed in the recess provided in the'lowerface of. the head for the upper end of the outer sash so as to give anupper finish to the window opening. This filler strip 31 maybeadvantageously'supplied with a drip groove to prevent moisturetraveling inward along the filler strip. A finishing stop 25, previouslyreferred to, provides additional security againstthc entrance 3 of theelements althoughit is not absolutely, necessary; The

upper guide 'channel27, as best shown in 'F1g.-4:,- has its side wallslnturned along theirlower'ed'ges, said edges being arranged to opposeeach'other at a slight.v distance apart as indicatedat 33 (Figut) so asto constitute of said channel a guide housing provided along the lowerface with the slot 34 between the edges 33.. The guide channel 27 isarranged to accommodate the rollers 35 which rollers are rotatably mounted upon the spindle 36 which is fixed in the arm 37 of an L-shapedbracket 38, the other arm 39 of which extends at right angles to the arm37 and is provided at 40 with screw holes for attachment by means of thescrews 41 to the edge ofthe sash. The spindle 36 has sufiicient lengthbetween the plate 37 and the roller 35 to allow for the edges 33 of theguide channel the spindle itself being accommodated within the slot at.

Upon the sill 2d of the window frame is secured a sill plate 42,upwardly flanged along its inner edge as indicated at as to provide aguiding rib for the lower edge of the sash. This rib 43 is spacedslightly outward from the sill stool andthe aforementioned stop 26. Uponthe lower edge of the sash adjacent its outer edge is secured a pivotplate at having an upturned positioning flange 45 to engage the outeredge of the sash. This pivot plate carries a pivot t6 downwardlyprojecting. Upon this pivot 46 is loosely mounted an elongated guideblock 47 by meansof an aperture 48 which engages over the pivot pin 46whereby to permit a rotary pivotal movement of the pin with reference tothe block and also a relative axial or vertical movement of the block onsaid pin. The lower face of the block is grooved at one side of thepivot as indicated at 49, said groove arranged to re lower corners ofthe sash one directly above the other, the axis of the pivot pin 46corresponding substantially with that of the roller spindle 36, the.opposite edge of the sash being hinged at 20 to the corresponding edgeof the next adjacent sash unit of the pair so that'as the two rollers 35of thepair are moved toward each other the continuity of the pair ofsash willbe broken at the hinge as indicated in dotted lines at theright hand end of Fig. 1, thus permitting the windows to open. At thehinged edges of the sash; is provided a handle 50'pivoted on the leaf52. for attachment by means of the screw holes 53 to the edge of thesash intermediate the regular hinges, this form of construction beingillustrated in'de tailinl ig. 10. r i

'An explanationlof the 'methodgof installing the window of the presentapplication will make clear many of its advantages over previouslydevised constructions. The suspending channel 27 and the sill plate 42having been placed in position at the top and bottom respectively of thewindow opening, after the requisite number of hangers 38 have beenassociated with the channel 27, their rollers being within the same, twoof the closure units are connected together at their adjacent edges bymeans of the hinges 20 and the handles 50 are placed in position. One ofthe hinged pairs of sash memhers is then positioned at the bottom withits guide block 47 taking over the rib 43 and with its pivot pin 46 inthe opening 48. The pair of sash is then brought to a vertical positionwith the upper edge of each embraced between the arms 37 and 39 of onebracket 38. WVhen properly positioned a line is drawn around the arm 39of the bracket and a proper mortise prepared for the reception of thesaid arm 39 to render the same flush with the edge of the sash. Thescrews 41 are then driven home and the mounting of the sash unit iscompleted. The casement window is now completely installed. It will beobserved that the mounting of all the hardware fittings is accomplishedwithout having to work from the confined space above the sash and thatwhen the windows are closed the hanging brackets are entirely concealedfrom View, the only hardware visible being the butts of the hinges andthe handle 50 provided for the operation of the sash. It will likewisebe observed that when the windows are wholly or partially opened, thebrackets are exposed to view and the screws 41 accessible in the eventit is desired to remove any one of the sash for replacement or repair.The provision for vertical play of the pivot pin 46 in the hole 48 ofthe block 47 insures that said block may travel back and forth along theguide rib 43 without any danger of disengagement therefrom even thoughsaid guide may be sagged in the central portion, the said blockremaining in constant relation to the guide and the pivot pin 46 playingup and down within the hole 48 to take care of any variations invertical dimensions of the space separating the suspending channel 27and the sill plate 42. This vertical play taken in connection with thepivotal mounting of the elongated block 47 on the pivot pin 46 and theoff-set disposition of the groove insures against binding ordisassociation of the parts.

It will be observed that I have provided a sliding casement window whichis especially adapted for ready association with the standard windowframes without requiring the taking out of the same and the substitutionof a special frame for the purpose; that the hardware fittings areconcealed from view except when the window is open, and are readilyaccessible to the workman when mounting and dismounting the sash; thatbinding and all danger of disassociation of the parts is avoided by theprovision for vertical, pivotal and lateral play between the sash andthe guiding block 47, rendering the window practically immune fromdifficulties arising after installation to which windows of this typehave been peculiarly susceptible.

l/Vhere, as show in Fig. 11, the flange of the sill plate 42 underliesthe stool 26, the installation is advantageously accomplished by placingthe required number of blocks 47 in position on the plate with theirgrooves 49 over the flange 43 and the sill plate is then shoved with theblocks beneath the overhanging edge of the stool, after which the sillplate is fixed in position by means of the screws. In this form ofconstruction, the overhang of the stool provides an additional safeguardagainst accidental disengagement of the block from the guiding rib wherethe sill may have sagged in any portion of its length.
